Abstract:

Soil salinity reduces the triticale biomass, research slightly salinization of land different factors on the yield of forage triticale, of saline on the cultivation of high yield and quality forage triticale provide a theoretical basis. Using four factors and three-level orthogonal design method, research the effects of different planting densities (B), the amount of base fertilizer (C), the amount of fertilizer (D) to affect three excellent forage triticale (Triticum secale) varieties(Strain)(A): ‘Hashi209’, ‘Hashi0442’, ‘Hashi0447’ yield of fresh grass, and analysis of the results of different combinations of fresh yield. Fresh yield of triticale density significantly affected , and between different densities significantly different, the other three factors had no significant impact on yield , various factors on the fresh yield of triticale were the degree of influence: Planting density>Variety>The amount of base fertilizer> the amount of fertilizer. In the test condition, suitable varieties for the ‘Hashi209’, seeding rate of 300 kg/hm2, use composite base fertilizer 300 kg/hm2, after cutting add tol urea fertilizer 75 kg/hm2.
